I they're not used in servers it's because they can't stand the higher amount of writing. And that depends on what you're doing with the server. If i made a server where I wanted fast disk access, but it wasn't written in huge quantities, I'd use SSDs. https://ark.intel.com/products/97164...#tab-blade-1-0 # Capacity 750 GB # Endurance Rating (Lifetime Writes) 41000 TBW # Mean Time Between Failures (MTBF) 2 million hours # Enhanced Power Loss Data Protection Yes === "I'm an enterprise product" That drive can be written end to end, about 55000 times, if you believe the endurance rating. There are also flash based storage subsystems with internal RAID, such that if a chip fails, another (unused) chip can be put in place of it, and rebuilt using redundancy info in the chip array. I think this is called RAIN. https://www.micron.com/~/media/docum...f_ssd_rain.pdf It's possible there are also flash drives (think of a 4U form factor), where flash chips are arranged on cards, and can be replaced hot when they fail. Take the top off, plug in a new card (wait for rebuild). These are products you won't find on the web, and if you have to ask the price, you can't afford one. (It's similar to PCI Express, where there are all sorts of whizzy PCI Express technologies out there, which aren't advertised on the web. Those might be used in HPC environments.) Most of the advertising we see, is for the "rubbish stuff" :-) Paul |
